CastToVector2f allows supported types to be explicitly coerced to an FVector2f or const FVector2f& This allows generic programming patterns that must operate on FVector2f given many input types
namespace UE { namespace Slate { const FVector2f & UE::Slate::CastToVector2f ( const FVector2f & InValue ) } }
